I know how you feel, my aunt is a very busy women she runs a farm and lives very far from me. I went 7 years without seeing her, untill she had time to visit this year she came in June and left by July 10th, she spent 4th of July with us. She had a baby which is 5 years old now and we met at her 4 years old. I just wish she would come more often down here. When she i felt the same way, i tried not to cry when she left but i could not help it thinking i might see her only 7 years from now and only for a month and a half But you are right the pain of a son is much more worse.
